# Btrfs Helpers for Arch/CachyOS

# ============================================================================

# Quick commands for btrfs filesystem management
|
||||
# CachyOS defaults to btrfs, so these are highly useful
|
||||
#
|
||||
# Commands:
|
||||
# btrfs-usage - Show filesystem usage
|
||||
# btrfs-subs - List subvolumes
|
||||
# btrfs-balance - Start balance operation
|
||||
# btrfs-scrub - Start/check scrub
|
||||
# btrfs-defrag - Defragment file or directory
|
||||
# btrfs-compress - Show compression stats
|
||||
# btrfs-info - Full filesystem info
|
||||
# btrfs-health - Quick health check
|
||||
